Abstract
Luminous signalling device (1) includes one or more light tubes (8) and focusing elements (2, 3, 4, 5, 6, 7) for focusing a light beam, these elements being capable of focusing a light beam coming from the light tube(s), the elements for focusing a light beam comprising several cylindrical lenses (2, 3, 4, 5, 6, 7), each cylindrical lens having a longitudinal axis lying parallel to a straight section (9, 10, 11) of the light tube. The straight sections (9, 10, 11) are oriented in several directions around a predetermined azimuthal axis (A), the number and the orientation of the straight sections being chosen so that the light beams coming from the straight sections and focused by the cylindrical lenses (2, 3, 4, 5, 6, 7) are directed in all azimuthal directions about the azimuthal axis.
Claims20
A light signaling device (1) that comprises:
- one or more light tubes (8);
- and
- a plurality of cylindrical lenses (2, 3, 4, 5, 6, 7) focusing a light beam of said light tubes,
- wherein, each cylindrical lens has a longitudinal axis (L1, L2) that is arranged in a parallel manner to a rectilinear segment (9, 10, 11) of a so-called light tube,
- said rectilinear segments (9, 10, 11) are oriented in a plurality of directions around a predetermined azimuth axis (A), and
- the number and the orientation of said rectilinear segments are selected such that the light beams that come from said rectilinear segments and that are focused by said cylindrical lenses (2, 3, 4, 5, 6, 7) are directed in all of the azimuthal directions around said azimuth axis.
